Coldroom dimensions - Internal coldwind_dimension_mode_setting_icon.png or External coldwind_dimension_mode_setting_icon_b.png?

The argument continues. Well perhaps not so much an argument but certainly a persistent debate.


In the United Kingdom at least cold room designs are generally conducted based upon external room dimensions. At Mistral our programs have followed this practice from the beginning, over 30 years ago. When desktop computers weighed a tonne and ran on steam, or so it seems to us now. We had always assumed this being due to coldrooms, smaller ones in particular, generally being constructed inside another enveloping building space. This is not how they do things on the Continent however. In most European countries cold rooms are usually designed, sold and discussed using internal dimensions. Mistral thus supplied its programs in mainland Europe accordingly.

Debate no more!

Now you can have it both ways. From 1st April* Coldwind Pro will have the facility to switch back and forth between designing with either internal or external room dimensions.

To minimize risk of confusion the program's operating dimension mode is clearly indicated at the top of the Room Designer form. To completely eliminate risk of potential and costly on-site errors calculation results filed in either mode will be respected and effectively 'locked' in whichever mode they were originally created in.

* No, not an April Fool's joke!

Cost to Mistral of redeveloping Coldwind Pro source code dimension routines and associated, linked functions. Circa 120,000 Euros.
